Sorry to reanimate a dead thread but, I am plagued by the 2-1 tranny jerk and wanted to know what is the best way of going about doing this? I have WinKFP. I don't have SSS. How difficult of a process is it? Also, in my research, I heard that you have to have the latest daten files for the E53. I have had no luck with locating / knowing what the latest files are. Hopefully one of you can shed some light on this for me. Thank you.
